bottom of the box first a substantial layer of moss, then a 
piece of -mosquito-bar the size of the box, then a layer of 
eggs, then another similar piece of mosquito-bar, then a layer of 
moss, then mosquito-bar and eggs again, and so on to the 
top. The layers of moss should be thick enough to effec- 
tually prevent the adjacent layers of eggs from touching each 
other, and this is about all that is necessary. The top layer 
of all should be considerably thicker. 
TRANSPORTATION OF THE EGGs. 
The whole secret of the successful transportation of sal- 
mon-eggs lies in observing this one rule, viz.: 
(1.) KEEP THE EGGS COLD. 
By cold, I mean as near the freezing-point as they can 
be kept without freezing. 1 cannot emphasize this point 
enough. If you pack the eggs properly, and keep them cold 
enough, you are perfectly certain, with the exercise of an or- 
dinary amount of common sense, leaving accidents out of ac- 
count, to take-them safely a month’s journey. There is no 
chance or uncertainty about it. Indeed, it is safe to say 
that if.1t were practicable ‘to. “keep + the’. temperature/aiig3 
deg. Fahrenheit, you could take salmon-eggs around the 
world alive. On the other hand, if you let them get warm, 
you are perfectly certain to lose them. 
This was undoubtedly the cause of the loss of the ship- 
ments of California salmon-eggs to Europe in the fall of 
1877. At some point between Sacramento and Liverpool the 
eggs, not, of course, through any conscious neglect of the 
messenger in charge, but undoubtedly without his knowl- 
edge, were allowed to get warm, and, as a necessary conse- 
quence, were lost. The disaster could not have resulted from
